tRFs and tiRNAs alter embryonic transcriptional cascades as paternal epigenetic factors in intergenerational inheritance of metabolic disorders, and tRNA modification defects are linked to diabetes. Arraystar's solution profiles tRNA expression, modifications, and tRF/tiRNA populations in metabolic research by sequencing, LC-MS, and PCR arrays.
tRNA and tRF/tiRNA layers in metabolic regulation
tRFs and tiRNAs, generated through precise biogenesis processes from tRNA, alter embryonic transcriptional cascades as paternal epigenetic factors in intergenerational inheritance of metabolic disorders [1]. Defects in tRNA modifications and modification enzymes are linked with human diseases such as diabetes and metabolic conditions [2].
Arraystar's metabolic syndrome & epigenetic inheritance solution combines tRNA-seq and tRF&tiRNA-seq to profile expression changes, LC-MS based tRNA modification analysis to quantify global modification levels, and the tRNA PCR array for high-throughput validation — connecting tRNA biology with metabolic programming and inheritance.
This solution profiles tRNA expression, tRNA modifications, and tRF/tiRNA populations in metabolic research, using tRNA-seq, tRF&tiRNA-seq, LC-MS, and PCR arrays. It supports studies of metabolic syndrome, diabetes, and paternal epigenetic inheritance of metabolic disorders.

tRNA and tRF/tiRNA in metabolism and inheritance
tRFs and tiRNAs, generated through precise biogenesis processes from tRNA, perform many biological functions as small noncoding RNAs (Fig. 1). They alter embryonic transcriptional cascades as paternal epigenetic factors in intergenerational inheritance of metabolic disorders [1].
Defects in tRNA modifications and modification enzymes are linked with human diseases such as cancers, diabetes, neurological syndromes, cardiac conditions, and mitochondrial-linked disorders [2]. tRNA modification profiles are key to establishing the link with the disease and tRNA molecular functioning.
tRNA and tRF&tiRNA populations are highly enriched in biofluids, much more so than microRNAs [3-4], supporting metabolic biomarker studies in serum and plasma.
